Whirlpool ED5KVEXVB 25.3 Cu. Ft. Side-by-Side Refrigerator Review$999.00
A refrigerator has to chill your food, then keep it at a constant temperature to preserve it as long as possible. If the temperature of the food varies, the food may spoil quicker. We found that this Whirlpool had good performance in this test, maintaining a very constant temperature over the several days of our test.
The graph above shows a sample of 12 hours of data from our tests (the full test runs over several days), and show how the refrigerator temperature remains mostly in the yellow zone, which is the Goldilocks zone for a fridge: not too hot, not too cold, but just right. It did have occasional temperature rises, though, which could eventually cause food to spoil.
The freezer was also mostly consistent in temperature, which helps to stop food from getting freezer burned. Again, there were some occasional sudden rises in temperature, but only very occasionally.
Your vegetables like to hide in cool, dark places where they won't get too dried out. That's why refrigerators have dedicated vegetable and fruit drawers, which we test using a fake vegetable (made from floral foam soaked in water). We put this into the vegetable drawer and check the weight over several days to determine how much water is lost to evaporation. We found that the this Whirlpool had slightly disappointing results here: our test vegetable lost just over a quarter of a gram of water per hour, which means that it dried our somewhat quicker than we like to see. So, don't expect your fruits and vegetables to stay moist and tasty in this refrigerator for more than a couple of days.
If the power at your home gets cut off, your food in the freezer is at risk. So, we test how long food will last in a refrigerator will last by allowing a block of fake food with a temperature sensor to freeze, then cutting off the power and seeing how quickly this block defrosts. For this Whirlpool, we found that this block was no longer frozen after 32 hours and 54 minutes. That is an acceptable time, but if you live in an area with frequent power cuts, you may want to spend more on a fridge with better insulation.
Fast freezing makes food last longer, so it is good to see that our fake food froze quickly in this refrigerator: it was frozen solid in 1 hour and 18 minutes. For this test, we placed the fake food in the compartment above the ice maker that is especially designed for this purpose, as it is right next to the cold air outlet.
